Why Stone Oak Homeowners Are Overpaying
Stone Oak’s overassessment risk stems from new construction inflating values for established neighborhoods. Builders in Heights at Stone Oak or Iron Mountain Ranch set premium prices that BCAD uses as comps for 1990s-era homes in original Stone Oak — homes that lack modern finishes, insulation standards, and smart-home features.
BCAD applies mass appraisal across all of Stone Oak, but a 1992 home in original Stone Oak has nothing in common with a 2024 build in Heights at Stone Oak. The 20+ sub-communities span everything from gated luxury to 1980s starter homes, and BCAD’s model treats them as one neighborhood.
The Comal ISD vs. NEISD boundary is another critical issue — homes on the Comal side face school taxes 22% higher ($1.2046 vs. $0.9822). And for properties in MUD or PID districts, lowering the base BCAD value reduces all tax layers simultaneously, making a protest even more valuable.
- New construction at premium prices pulls up BCAD comps for established homes
- A 1992 home in original Stone Oak should not be valued like a 2024 build in Heights at Stone Oak
- MUD/PID layering ($0.08–$0.55+/per $100 extra) makes base value reductions more impactful
- Comal ISD side faces school taxes 22% higher than NEISD side
- BCAD valuations were off by an average of $94,000 on verified 2025 MLS sales
The 2025–2026 Reappraisal Reprieve
BCAD adopted a biennial reappraisal plan: market values settled through protest in 2025 carry forward unchanged to 2026 unless new construction or clear-and-convincing evidence warrants a change. A successful protest now could lock in lower values for two full tax years.
How We Build Your Stone Oak Case
Stone Oak’s 20+ sub-communities mean BCAD lumps wildly different homes together. We don’t.
Sub-Community Comparables
We pull comparable sales from the same sub-community and same construction era — never mixing 1990s stock with 2020s builds that inflate your assessment.
Unequal Appraisal Analysis
We compare the same model home valued differently across Stone Oak’s 20+ sub-communities, demonstrating systematic inequity in BCAD’s approach.
Condition Adjustments
Older phases show wear that new construction doesn’t have. We document dated finishes, original systems, and structural aging that BCAD’s model ignores.
MUD/PID Impact Analysis
For properties in MUD or PID districts, we show how lowering the base value creates cascading savings across every tax layer — making the reduction even more valuable.
What It Costs in Stone Oak
On a median Stone Oak home assessed at $435,248 with a combined rate of approximately $2.268 per $100, the estimated annual tax bill is roughly $9,871. A conservative 10% reduction in assessed value would save approximately $987 per year. Our fee: 40% of that first-year savings, or about $395. For properties in MUD/PID districts, the savings are even larger since the reduction applies to every tax layer.
No upfront cost. No minimum fee. No auto-renewal. You only pay 40% of first-year savings. Year 2 and beyond, you keep 100%. See the 5-year math →
Frequently Asked Questions
Can my taxes go up if I protest?+
No. Texas Tax Code §41.43 prohibits the appraisal district from raising your assessed value as a result of a protest. The worst outcome is your value stays the same. There is zero risk to filing.
What is a MUD and how does it affect my taxes?+
A Municipal Utility District (MUD) is a special taxing district that adds $0.08–$0.55+ per $100 on top of your regular taxes to fund infrastructure like water, sewer, and drainage. When we reduce your base BCAD value, the savings cascade across your MUD tax, PID tax, and all other tax layers simultaneously.
Am I in NEISD or Comal ISD?+
Most Stone Oak homes are in North East ISD ($0.9822/$100). Some northern portions fall in Comal ISD ($1.2046/$100) — a 22% higher school tax rate. Check your BCAD notice to verify your school district. If you’re on the Comal side, accurate assessment is even more critical.
Why are newer homes being used as comps for my older home?+
BCAD’s mass appraisal model groups properties by neighborhood and ZIP code, which means a 2024 new build in Heights at Stone Oak can influence the assessed value of a 1992 home in original Stone Oak. We fight this by pulling comps exclusively from your sub-community and construction era.
What is the filing deadline?+
May 15, 2026 (or 30 days after BCAD mails your Notice of Appraised Value, whichever is later). Filing can be done online, by mail, or in person.
Does ATD handle the entire process?+
Yes. We handle all four stages: informal hearing, ARB hearing, binding arbitration, and district court. We file the protest, build the evidence package, attend all hearings, and negotiate on your behalf.
